ATTORNEY WITNESS Patented May 26, 1936 EJETE STATEEi Tr OFFICE 1 Claim.

This invention relates to window sashes and frames and has for an object to provide screen sashes and storm sashes which are selectively foldable and slidable into storage compartments built into the window frame, the pivots being disposed intermediate the ends of the sash elements in contrast to being disposed at the line of juncture of the elements, whereby a more balanced arrangement will be produced and jamming or sticking of the sash elements positively prevented.

A further object is to provide a device of this character in which the sash elements in folded relation lie one against the other transversely to or at a right angle to the track in which the pivots are carried so as to be stored in minimum space and whereby the sash elements may be passed edge on into the storage compartments at the sides of the window frame to be quickly stored or quickly moved to operative position.

A further object is to provide a device of this character in which the screen sashes and storm sashes may be operated from inside the room, the window pane sashes for this purpose being folded in the same manner as the screen and storm sashes to permit access to the latter.

A further object s to provide a device of this character which will be formed of a few strong, durable and inexpensive parts, which may be manufactured at minimum expense, and which will not easily get out of order.

With the above and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claim without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings forming part of this specification,

Figure l. is a front elevation of the improved window frame and sash construction looking from inside the building.

Figure 2 is a cross sectional view taken on the line 2-2 of Figure 1 showing the hinges which connect the folding elements of the screen sashes.

Figure 3 is a cross sectional View taken on the line of Figure 1 showing the folding elements of the window sashes.

Figure 4 is a cross sectional view taken on the line 44 of Figure l with the window sashes in partly folded position to permit access to the screen sashes, and showing the storm sashes stored in one of the storage compartments.

Figure 5 is a vertical sectional view taken on the line 5--5 of Figure 1, showing the tracks and pivots for the sashes at the top of the window frame, and

Figure 6 is a vertical sectional view taken on the line 66 of Figure 1 showing the tracks and pivots for the sashes at the bottom of the window frame.

Referring now to the drawings in which like characters of reference designate similar parts in the various views, I!) designates the uprights of a window frame, each being open on the inner side and closed by a hinged door H to provide a storage compartment, as best shown in Figure 4. The head 52 and the sill I3 of the window frame are provided with tracks M and !5 respectively, each track being preferably a metal tube of rectangular cross section having a slot l6 to receive the pivots of the folding elements of the screen and storm sashes hereinafter described. Likewise, the head and sill are provided with similar tracks if and i8 having slots H] to receive the pivots of the window sashes as will presently be described.

The screen sash elements 2|] are hinged together at their longitudinal edges by double swinging hinges 25 of the three leaf type, best shown in Figure 2, and midway between the edges of each sash element pivots 22 and 23 slidably connect the sash elements to the upper and lower tracks id and I5, as best shown in Figures 5 and 6. By referring to Figure 4 it will be seen that the end portions of the track are offset obliquely as shown at 24 to dispose the extreme end portions 25 of the track at the center of the corresponding storage compartment. The purpose is to permit the screen sash elements to be slid into or out of the storage compartment on one side of the window frame and folded to lie flat against each other at a right angle to the tracks at the top and the bottom of the compartment whereby the screen sash elements occupy minimum space when stored and at the same time may be easily collapsed into the compartment or slid out of the compartment to ex- 45 tended position and during such sliding movement because of the pivots being positioned midway between the edges of the sash elements the sash elements will be nicely balanced to prevent jamming.

The storm sash is formed of elements 26 hing-- edly connected together as just described to fold fiat upon each other and be compactly stored in the storage compartment at the right of the window frame as shown in Figure 4. The storm sash elements may be formed simply of boards or may be equipped with panes, but in either event when'the screen sashes are collapsed into the screen storage compartment the storm sash elements may be slid out of the storm sash storage compartment to operative position as will be together by the double swinging hinges 30 of the three leaf type and are pivotally and slidably mounted upon the upper and lower tracks I! and I8 by means of pivots 3i and 32, as best shown in Figures 5 and. 6. The pivots are arranged midway between the edges of each sash element so that the elements are nicely balanced and jamming eliminated.

"In operation assuming that the screen sashes are'in use'and it is desired to substitute the storm sashes, for example, the window sashes 29 may be folded to incline at acute angles to each other, as best shown in Figure 4, whereupon the door -ll of the screen storage compartment'may be rocked open and the screen sash elements may then be slid along the tracks and folded to lie flat against eachrother in the storage compartment.

The door ll may now be closed. The door of the storm sash storage compartment may now be opened and the storm sash elements slid out of the compartment along the tracks to the position previously occupied by the screen sash elements. To store the storm sash elements and move the screen sash elements to operative position the above procedure is reversed.

From the above description it is thought that the construction and operation of the invention Will be fully understood without further explatogether at the vertical edges and pivotally connected at the centers of the upper and lower edges to the other pair of tracks for folding upon each other to permit access to the first named sashes.
